780 pH Meter - top-level pH meter

Flexible and easy to operate

Metrohm's new pH meter generation offers numerous possibilities. In addition to the general functions for measuring pH, potential and temperature, the new pH meters boast features such as the optimized, GLP-compliant electrode test as well as monitoring and service intervals. also the stirrers have been optimized. They are now directly controlled by the pH meter via the MSB interface (MSB = Metrohm Serial Bus). The stirring speed is set on the pH Meter. This assures that measurements are always carried out under the same conditions. You can choose between the 801 Magnetic Stirrer and the 802 Rod Stirrer.

Practical quality control

  • Inherent quality control tool: pH electrode test for standard electrodes, gel electrodes and electrodes for non-aqueous media
  • Automatic temperature compensation for pH measurements
  • Automatic electrode test with graphics printout for pH electrodes (GLP, ISO 9000)
  • Automatic recognition of the following buffer sets: Metrohm, Precisa, Merck, Fisher, Fluka BS, Mettler, Baker, Beckman, Hamilton, Radiometer, DIN/NIST (NBS) as well as special buffers
  • Automatic recognition and control of stirrer via "Metrohm Serial Bus"
  • Easy operation thanks to large display
  • Recall of stored calibration data including curves
  • Entering of calibration interval with reminder
